Worked on the bevyengine/bevy repository to address a critical race condition in Material2d rendering, focusing on dynamic texture stability during window resizing. Using Rust and leveraging expertise in graphics programming and game development, implemented dependency tracking so that PreparedMaterial2d correctly references the latest GpuImage when creating bind groups. This approach ensured that after a window resize, the rendering pipeline no longer used outdated TextureViews, preventing visual inconsistencies. The solution was validated through targeted render-to-texture and resize scenarios, resulting in more reliable dynamic texture workflows and improved rendering stability for Bevy applications utilizing Material2d and render-to-texture features.

April 2026: Fixed a critical race in Material2d rendering where a GpuImage update could race with PreparedMaterial2d, causing an outdated TextureView to be used after window resize. The change registers GpuImage as a dependency of PreparedMaterial2d, ensuring the bind group always uses the latest GpuImage reference. This stabilizes render-target textures during resize across Bevy apps leveraging Material2d and render-to-texture flows.
